What this skill is

Even numbers can be split into two equal groups, or into pairs, with none left over. Odd numbers always leave one.

When it comes up: Second grade.

The mistake to watch for

Looking at the first digit. Only the ones digit decides: 0, 2, 4, 6 and 8 mean even.

How to help

Make pairs with small objects. If one is left over, the number is odd.

Next: Skip counting and multiplication.

A worked example

Is 47 even or odd? Look at the ones digit, 7. Odd numbers end in 1, 3, 5, 7 or 9, so 47 is odd. 48 ends in 8, so 48 is even.
